Study of creep behavior of load cells.For most force measurement applications,the user of a load cell assumes a one-to-one correspondence between the applied force and the load cell indicator reading.Thus the time variation in response due to creep is a source results for this questionWhat happens to the wire during the creep experiment?What happens to the wire during the creep experiment?Under some circumstances, we may return several hours (or several days or several weeks) later and find that the weight has gradually stretched the wire.This deformation at elevated temperature under constant load is called creep.It depends on the wire material and the temperature of the room.Creep Experiment Materials Science and Engineering results for this questionWhat is the unloading creep behavior of soft soil?What is the unloading creep behavior of soft soil?The unloading creep behavior of soft soil under lateral unloading stress path and excess pore water pressure is the core problem of time-dependent analysis of surrounding rock deformation under excavation of soft soil.The soft soil in Shenzhen,China,was selected in this study.Experiment Study of Lateral Unloading Stress Path and Excess Pore Wat
